One-hand operable end fitting connector assembly

ABSTRACT

An end fitting connector assembly includes an end fitting having a first end, a second end and a through opening that extends in a direction that is transverse to an end fitting axis extending through the first and second ends and in which the through opening is defined by a peripheral wall. An elastically deformable race fitted into the through opening of the end fitting includes an exterior surface that engages the peripheral wall and an interior surface configured to provide snap fitting engagement with a spherical ball mount. At least one feature retaining the race within the end fitting creates an increased disassembly force, which may prevent disassembly without employing a release tool or release feature. The interior and exterior surfaces of the race can include spherical surfaces for conforming to the spherical ball and the peripheral wall of the end fitting.

CROSS REFERENCE TO RELATED APPLICATION

This application is a divisional application of U.S. Ser. No.14/571,587, filed on Dec. 16, 2014, the entire contents of which areincorporated by reference.

TECHNICAL FIELD

This application is generally directed to the field of componentmanufacture and more specifically directed to an end fitting connectorassembly that permits one-handed assembly for efficiently and reliablyenabling use in various structural applications.

BACKGROUND

So called “quick connect” end fitting connectors are known for use invarious assemblies, such as linear or hydraulic rate control or actuatorassemblies. In a typical configuration, an axially movable rod end of arate control or an actuator component is engaged with an end fitting,such as a clevis, to provide engagement with a spherical ball mount thatis attached to a mated structure.

By way of example and referring to FIG. 1, there is shown a prior artend fitting connector assembly 10 that is used to interconnect anaxially movable rod end 14 with a structure, such as a stowage bin of astowage compartment typically found in commercial aircraft, the latterincluding a retainer plate 18. The retainer plate 18 includes aplurality of attachment holes 22, which are spaced and configured toreceive fasteners (not shown) for fixedly securing same to a structure(not shown). Disposed at the movable rod end 14 is a clevis lug 28,which is defined by a substantially T-shaped body. The clevis lug 28 isconfigured for engagement with a corresponding T-shaped receiving slot32 of a clevis mount 40 that is pivotally secured to the retainer plate18. In operation, the clevis lug 28 is mated to the clevis mount 40, andmore specifically the T-shaped receiving slot 32, wherein the clevis lug28 includes a spring retention clip 44 at its distal end that createspositive engagement upon attachment to the clevis mount 40.

When properly engaged, this end fitting connector assembly 10 does notpermit disassembly without the aid of a release tool (not shown).According to this version, the release tool can be introduced into theT-shaped receiving slot 32 and more specifically into direct engagementagainst the spring retention clip 44 to compress same and enable theclevis lug 28 to be removed from the T-shaped receiving slot 32 of theclevis mount 40.

There is a general need in the field to simplify the design of endfitting connectors, such as those shown in FIG. 1, but withoutsacrificing reliability. There is a similar need to provide an endfitting that enables one handed assembly, but prevents disassemblypreferably without the use of a tool or other release feature.

BRIEF DESCRIPTION

Therefore and according to one aspect, there is provided an end fittingconnector assembly comprising an end fitting having a first end, asecond end and a through opening transversely disposed in relation to anaxis passing through the first and second ends, the through openingbeing defined by a peripheral wall. An elastically deformable race isfitted within the circular opening of the end fitting, the race havingan outer surface that engages the peripheral wall and an inner surfacethat is configured to engage a spherical ball mount.

In at least one version, the end fitting connector assembly furtherincludes at least one feature that maintains the elastically deformablerace in a predetermined position relative to the transverse throughopening of the end fitting, such that the spherical ball mount cannoteasily be removed following assembly.

In one version, one of the race or the peripheral wall includes a raisedcircumferential ridge and the other of the race and the peripheral wallincludes an annular groove sized for receiving the raisedcircumferential ridge and defining the features for retaining the racein the predetermined position.

The elastically deformable race can be defined by a ring-likeconfiguration having a slit along the circumference thereof that createsa split ring configuration. The elastically deformable race or theannular groove of the peripheral wall of the end fitting can furtherinclude at least one raised circumferential ridge, which is configuredand sized to engage an annular groove formed in the other of theperipheral wall of the end fitting and the race. In one version, atleast one of the annular groove and the raised circumferential ridge canbe defined by square edges, while in another version the annular groovecan be defined by tapered walls that are aligned with the raisedcircumferential ridge in order to create an additional compressive forceand/or a “locking” feature that increases the force required forassembly or disassembly and in at least some instances requiring a toolor other release feature.

In another version, the outer surface of the elastically deformable raceand the peripheral wall of the through opening of the end fitting caninclude aligned grooves though which a locking element can betransversely disposed to effect disassembly by effectively locking therace with the end fitting and preventing the race to translate alongwith the ball mount. Based on the spherical or angled surfaces of thesecomponents, disassembly can be effected. The locking element can beintegrally disposed within the end fitting or can be provided separatelyin which the end fitting is configured for accepting the locking elementand can be engaged for release by a tool.

Though the race can be made from plastic, it may also be manufacturedfrom other suitable materials, including metal, to serve the intendedfunctionality of being elastically deformable as discussed herein. Forexample and according to at least one version, an elastically deformablerace can be defined by a metal body defined by a radially protrudingcenter portion and a pair of opposed axial ends. Each of the axial endsinclude a series of spaced castellations that form cantilevered springsabout the periphery of the end fitting when the race is attachedthereto. Via the cantilevered springs, a ball mount can be assembled andwherein the springs form a resistive force to prevent disassembly.

In yet another version, the peripheral wall of the end fitting caninclude a pair of recessed portions that are aligned with outwardlyextending end portions of the race and configured to increase the amountof force that is required for disassembly.

According to another aspect, there is provided a method for enablingone-handed operation of an end fitting connector assembly, the methodcomprising:

providing an end fitting having a first end, an opposing second end anda through opening between the first and second ends that is transverseto an axis extending between the first and second ends, the throughopening further defining a peripheral wall; and

providing an elastically deformable race that is sized to be engagedwithin the through opening of the end fitting, the race having anexterior spherical surface in contact with the peripheral wall and aninner surface configured to directly and snapfittingly engage aspherical ball mount.

In at least one embodiment, at least one of the elastically deformablerace and the peripheral wall of the end fitting are provided with atleast one engagement feature for retaining the race in a predeterminedposition. In one such version, the engagement feature includes a raisedcircumferential ridge of one of the race and peripheral wall thatengages an annular groove of the other.

The annular groove can include tapered or angled surfaces to provide alocking effect.

In yet another version, the outer surface of the elastically deformablerace and the peripheral wall of the through opening of the end fittingcan include aligned grooves though which a locking element can betransversely disposed to effect disassembly by effectively locking therace with the end fitting and preventing the race to translate alongwith the ball mount. Based on the spherical or angled surfaces of thesecomponents, disassembly can be effected. The locking element can beintegrally disposed within the end fitting or can be provided separatelyin which the end fitting is configured for accepting the locking elementand can be engaged for release by a tool.

The elastically deformable race can be made from plastic and can furtherbe defined by a split-ring configuration. In one such version, a slit isprovided in the race to enable elastic deformation. This slit can bedefined, for example, by a scarf cut. In at least one version, the scarfcut can be angled.

According to yet another aspect, there is provided a rate control or anactuator comprising a rod member having at least one end, and an endfitting connector assembly attached to the at least one end of the rodmember. The end fitting connector assembly comprises an end fittinghaving a first end, a second end and a through opening extending in adirection that is transverse to an axis passing through the first andsecond ends, the through opening defining a peripheral wall; and anelastically deformable race disposed within the through opening of theend fitting and having a substantially spherical exterior surfaceengaged with the peripheral wall, at least one of the race or the endfitting having a feature that retains the race in a predeterminedposition, the race having a substantially spherical interior surfaceconfigured for positive engagement with a spherical ball mount.

In one version, one of the race or the peripheral wall includes a raisedcircumferential ridge and the other of the race and the peripheral wallincludes an annular groove sized for receiving the raisedcircumferential ridge and defining the features for retaining the racein the predetermined position.

The elastically deformable race can be defined by a ring-likeconfiguration having a slit along the circumference thereof that createsa split ring configuration. The elastically deformable race or theannular groove of the peripheral wall of the end fitting can furtherinclude at least one raised circumferential ridge, which is configuredand sized to engage an annular groove formed in the other of theperipheral wall of the end fitting and the race. In one version, atleast one of the annular groove and the raised circumferential ridge canbe defined by square edges, while in another version the annular groovecan be defined by tapered walls that are aligned with the raisedcircumferential ridge in order to create an additional compressive forceand/or a “locking” feature that increases the force required forassembly or disassembly and in at least some instances requiring a toolor other release feature.

In another version, the outer surface of the elastically deformable raceand the peripheral wall of the through opening of the end fitting caninclude aligned grooves though which a locking element can betransversely disposed to effect disassembly by effectively locking therace with the end fitting and preventing the race to translate alongwith the ball mount. Based on the spherical or angled surfaces of thesecomponents, disassembly can be effected. The locking element can beintegrally disposed within the end fitting or can be provided separatelyin which the end fitting is configured for accepting the locking elementand can be engaged for release by a tool.

One advantage realized by the foregoing assembly design is that ofsimplicity in that fewer parts are utilized than previously known endfitting assemblies having similar functionalities. As a result, theherein described end fitting connector assembly is both simpler andcheaper to manufacture/fabricate.

Another advantage provided by the herein described assembly is ease inuse, as compared with previously known end fitting assemblies. Simpleone-handed operation is assured during assembly of the ball mount to thejoint. In at least one version, disassembly can be readily conducted.According to another version, the force required to disassemble the ballfrom the assembly can be made considerably higher than the forcerequired to assemble for example, requiring a tool or other releasefeature to effect disassembly.

Yet another advantage is that the herein described end fitting assemblyis symmetrical such that the formed joint can be made and/or unmade fromeither side or direction of the end fitting.

Still another advantage is that of improved reliability since relativelyfragile components, such as the herein described elastically deformablerace, are protected within the end fitting, the latter acting as acontainer or receptacle.

Still further, yet another advantage realized is that no special toolingis required to assemble the race to the end fitting.

The herein described assembly is also lighter than prior known connectorassemblies.

Furthermore, the herein described concepts can further be applied toliterally any form of connection including cylinder ends, stays, strutsand the like for which a quick connect fitting is desired that providesretention about a ball or similar mount, while providing some degree ofpermissible misalignment.

These and other features and advantages will be readily apparent fromthe following Detailed Description, which should be read in conjunctionwith the accompanying drawings.

Referring to FIGS. 2-5, an end fitting connector assembly 100 made inaccordance with a first exemplary embodiment is defined by an endfitting 110, including a clevis or other similar component. The endfitting 110 is defined by a fitting body having a proximal end 111 and adistal end 113, in which a through opening 114 extends in a directionthat is transverse to a center axis 115 of the end fitting 110 extendingthrough the proximal and distal ends 111, 113. According to thisembodiment, the end fitting 110 is fabricated from a structuralmaterial, such as stainless steel or an aluminum alloy though it shouldbe noted that other suitable materials, such as a hard and durableplastic, can alternatively be used for purposes of manufacture of thiscomponent. The transverse through opening 114, according to thisspecific embodiment, is substantially circular and defined by a centeraxis 148, as well as a peripheral wall 118 forming an outer radialboundary of the through opening 114. As discussed herein, the centeraxis 148 also defines an assembly axis for purposes of the end fitting110 and all components mounted within the through opening 114. Accordingto this exemplary embodiment, an annular groove 120 is disposed inapproximately the center of the peripheral wall 118 between opposingopening ends 117, 119 of the through opening 114. The proximal end 111of the end fitting 110 in accordance with this embodiment includes anengagement portion 127 that is configured to fixedly support one end ofa cylindrical rod 126.

The end fitting connector assembly 100 further includes a race 130 thatis configured to be positioned within the transverse through opening 114of the end fitting 110. According to this specific embodiment and asshown more clearly in FIGS. 6-8, the race 130 is a ring-like memberhaving an outer or exterior surface 134 and an inner or interior surface138 in which the outer surface 134 of the race 130 is configured toengage the peripheral wall 118 of the end fitting 110 in an elasticallydeformable manner. According to this embodiment, the race 130 ispreferably made from a sufficiently flexible and durable plasticmaterial, such as acetal although other elastically deformable materialscan be utilized. A slit 142 is formed in the race 130, creating a splitring configuration. According to this specific embodiment and as moreclearly shown in FIGS. 7 and 8, the slit 142 is formed by means of ascarf cut formed preferentially at an angle α relative to the centeraxis 139 of the race 130, which when assembled is coaxial with the axis148 of the through opening 114. According to this embodiment, the angleα is about 15 degrees, although this parameter can be suitably varied.The exterior surface 134 of the race 130 is largely defined by aspherical or substantially spherical configuration 150, as well as araised circumferential ridge 154 disposed at approximately the center ofthe race 130 and substantially aligned along the axis 115 at the time ofassembly of the end fitting 110. Alternatively and in lieu of beingspherical, the exterior surface 134 of the race 130 can be defined usingangled surfaces (not shown) disposed to either side of the annular ridge154. Typically, a suitable range of angles can be about 5 to about 30degrees.

According to this specific embodiment, the elastically deformable race130 is defined by an outer diameter (excluding that of thecircumferential raised ridge 154) that is slightly smaller than that ofthe diameter of the center opening 114 of the end fitting 110. Thediameter selected for use should be based on several factors including,but not limited to the desired amount of installation and retentionforce as well as load and wear capacity. In any case, however, thissizing should permit the elastically deformable race 130 to expandsufficiently to permit installation and removal of the ball mount 170.As shown in FIG. 3, the scarf cut defining the slit 142 permits theelastically deformable race 130 to be installed into the transversethrough opening 114 of the end fitting 110 by elastically deforming therace 130 and more specifically elastically curling the race 130 to asmaller diameter and then allowing expansion once the race 130 is in apredetermined position. According to this embodiment, the formed splitring configuration as well as the substantially spherical outer surface134 permits the race 130 to be assembled and secured with the raisedcircumferential ridge 154 being positively engaged with the annulargroove 120 of the end fitting 110, thereby fixing the race 130 into thepredetermined position depicted in FIG. 10.

Referring to FIGS. 3-5 and 10, a ball mount 170 having a spherical outersurface 174 over at least a portion thereof can then be snap-fittedwithin the end fitting connector assembly 100 and more specificallyprovide positive retaining engagement between the substantiallyspherical inner surface 138 of the race 130 and the outer sphericalsurface 174 of the ball mount 170.

When assembled and according to FIGS. 9 and 10, the transverse throughopening 114 of the end fitting 110 provides a container or receptaclefor the elastically deformable race 130, supporting the race 130 andprotecting it from damage, wherein a connective link is provided to thedevice that the herein described assembly 100 is attached. The endfitting 110 also limits how much the race 130 may open at the slit 142such that, once the outer diameter of the race 130 contacts the innerdiameter face of the transverse center opening 114, the race 130 mustelastically expand at one or the other end in the race 130 (i.e.,proximal to the ends 117, 119, FIG. 10) as the ball mount 170 enters orexits. If the race 130 is not adequately restrained within the endfitting body 110, the race 130 would simply open at the slit 142 withrelative ease and be rendered relatively ineffective in restraining theball mount 170. In other words, the fitting body 110 restrains the race130 such that it acts almost as though the slit 142 was not present andthe smaller diameter opening on either side of the race 130 musteffectively “snap” over the larger diameter of the ball mount 170.

As noted and though the end fitting 110 resembles a clevis, it may takeother suitable forms. The elastically deformable race 130, which can bemade according to this embodiment from a moldable durable plastic, formsa “socket” into which the ball mount 170 is installed and retained. Whenattached, the ball mount 170 provides a 360 degree range of motion aboutthe center axis 148 of the transverse through opening 114 of the endfitting 110, the ball mount 170 providing a compressive force againstthe race 130 and engaging same, the race 130 being retained by the endfitting 110. In addition, a small amount of perpendicular motion mayalso be permitted (typically on the order of about 5 degrees) to allowfor misalignment. The ball mount 170 may be part of a stud oralternatively can be part of a bracket or other assembly. The ball mount170 may be permitted to rotate, but such rotation may not be necessarydepending on the specific application or use of the assembly.

In operation and as shown in FIGS. 2-5, 9 and 10, the joint is createdby snap fitting the assembled race 130 over the ball mount 170, or bysnapping the ball mount 170 into the end fitting connector assembly 100.This assembly can be performed using hand force by a single person andwithout requiring the use of tools or persons in which one of the twoend pieces of the assembly 100 is already held stationary or resting ona support or table (not shown). The end fitting 110 and the ball mount170 engage one another along their aligned central axes. Separation ofthe created joint can be effected by pulling the ball mount 170 or theend fitting 110 apart in the opposite direction.

In lieu of the raised circumferential ridge 154, the race 130 may bemanufactured with a significantly wider ridge on its outer diameter thatis configured to be engaged within a mating groove feature in the endfitting 110 in a snap fitting configuration. The latter type ofretention is useful for insuring that disassembly will require a largerforce than the force enabling the snap fit of the components.

Moreover and by profiling the faces of the annular groove 120 of the endfitting 110, a camming action can be created such that the forcerequired for dissasembly is extremely high, as compared to the assemblyforce, thereby effectively preventing the joint from being easilydisassembled.

One example of the foregoing design that includes a cammed annulargroove 120 is shown in FIGS. 11(a)-12(b). For purposes of thisdiscussion, similar parts are labeled with the same reference numeralsfor the sake of clarity.

FIG. 11(a) depicts an end fitting 110, in section, having a throughopening 114 and peripheral wall 118 having the tapered annular groove120. Depending on the desired retention force, a suitable angle for thetaper may be greater than or less than 45 degrees, with the groove 120having a minimum width at the bottom of the groove 120, and a maximumwidth at the top of the groove 120. Other than the taper in the groove120, the end fitting 110 may be literally identical to that previouslydescribed in detail with regard to FIGS. 2-5, 9 and 10.

FIG. 11(b) illustrates the assembly of the elastically deformable(preferably plastic) race 130 to the end fitting 110 and morespecifically to the through opening 114. As noted previously and forpurposes of this discussion, the race 130 includes each of thepreviously described elements depicted in FIGS. 6-8 and is literallyidentical thereto. More specifically, the race 130 includes an outersurface 134 and an inner surface 138, each of the foregoing surfacesaccording to this embodiment being defined as substantially sphericaledges extending along the direction of the through opening 114 andconfigured for engagement with the peripheral wall 118 of the throughopening 114. As in the preceding, the elastically deformable race 130has a slightly smaller outer diameter (with the exception of a raisedcircumferential ridge 154) than the diameter of the through opening 114wherein a slit 142, FIG. 12(a), enables the race 130 to be curledelastically. This dimensioning permits the raised circumferential ridge154 on the outer surface 134 of the race 130 to be aligned with theangled surfaces of the annular groove 120 of the peripheral wall 118 ofthe end fitting 110, thereby placing the elastically deformable race 130in a predetermined position.

FIG. 11(c) illustrates the further attachment of a spherical ball mount170 to the connector assembly 100 in which the inner surface 138 of therace 130 substantially conforms to the outer surface 174 of thespherical ball mount 170 and in which the ball mount 170 can beadvantageously installed (or disassembled) in either axial direction194(a) or 194(b) based on the symmetry of the components. FIGS. 12(a)and 12(b) illustrate separate sectioned views of this assemblage as wellas the connection of a rod end 126 within an engagement portion 127 ofthe end fitting 110.

In operation and once installed, the angled surfaces of the annulargroove 120 create a camming action. This action based on axial movementof the ball mount 170 in either the direction 194(a) or 194(b) increasesthe force required to disassemble the ball mount 170. More specifically,the elastically deformable race 130 is thereby configured to move withthe ball mount 170, which maintains the maximum engagement of the innersurface 138 of the race 130 with the outer spherical surface 174 of theball mount 170.

Referring to FIGS. 13(a)-13(c), one exemplary use of the hereindescribed end fitting connector assembly 100 is depicted in which a ratecontrol is defined by a cylindrical section 180 having the movable rodend 126 at one end, which is securely mounted within the engagementportion 127. Attached to a fixed opposite end of the cylindrical section180 is an end fitting 186, the latter component being substantiallysimilar to the end fitting 110 other than being attached to a stationaryportion of the cylindrical section 180.

For purposes of assembly and as shown in FIGS. 13(a) and 13(b), theelastically deformable race 130 is attached to the respective endfittings 110, 186 in the manner previously described wherein the race130 is elastically curled and moved into the defined transverse throughopening 114 with a raised circumferential ridge 154 of the race 130being aligned and secured within a defined annular groove on aperipheral wall 118 of the through opening 114 of the end fitting 110.

As further shown in FIGS. 13(b) and 13(c), each of the assembled endfittings 110, 186 can then be snap fitted to respective spherical ballmounts 170, each of the latter components including a retainer plate 184having attachment holes 188 for securing the ball mount 170 usingfasteners (not shown) to respective structures (not shown) in order tocomplete the assembly. As shown, each of the ball mounts 170 are shownbeneath the cylinder section 180. Alternatively, it should be understoodthat the ball mounts 170 could be positioned directly above the cylindersection 180 as shown, given the symmetrical relationships of theassembled race 130 and transverse through opening 114 of the hereindescribed end fittings 110, 186.

Though a ball having a spherical surface over at least a portion thereofis necessary for purposes of securement of the end fitting connectorassembly described herein, the remaining features of the ball mountitself can be made according to a number of configurations. For example,different mounting configurations for the ball itself can be utilized,as shown for example in FIGS. 14(a) and 14(b), in which an alternativeball mount 270 includes a spherical ball end 274, similar to thosepreviously described, that is integral to an axial threaded portion 278in lieu of a retaining plate 184, FIG. 13(a), on either or both sides ofthe assembly. It will be understood that other suitable variations canbe contemplated including stud, plate or other variations.

Various other end fitting connector assembly designs are possible. Forexample and as depicted in FIG. 15, another end fitting connectorassembly 300 is partially shown in section. Similarly to previouslydescribed versions, the end fitting connector assembly 300 includes anend fitting 310 having a proximal end, a distal end and a throughopening 314 that is transverse to an end fitting axis extending throughthe proximal end and the distal end, the through opening 314 beingappropriately sized for receiving and retaining an elasticallydeformable race 320. According to this version, a peripheral wall 318 ofthe through opening 314 includes a pair of recessed portions 330 definedat respective first and second ends 317, 319 of the through opening 314.The elastically deformable race 320 is a ring-like member preferablymade from a flexible and durable plastic having a pair of opposingoutwardly directed peripheral end portions 324 that are configured forengagement within the recessed portions 324 of the through opening 314of the end fitting 310. As shown, a ball mount 340 (partially shown) issnap-fitted within the through opening 314, the ball mount 340 having aspherical outer surface 344 that engages the inner surface of the race320 and elastically deforms same to create positive engagement. Wheninitially fitted as shown in FIG. 15, the inner surface of theelastically deformable race 320 substantially conforms to the outerspherical surface 344 of the ball mount 340 while the center portion ofthe outer surface of the race 320 is further caused to directly engagethe peripheral wall 318 of the through opening 314 of the end fitting310, thereby positively retaining the ball mount 340 to the end fittingconnector assembly 300.

According to this embodiment and following assembly, movement of theball mount 340 in the axial direction 348 causes a rearward peripheralend portion 330 of the race 320 to engage against a shoulder 336 of theperipheral wall 318 adjacent the recessed portion 330 of the throughopening 314, preventing the elastically deformable race 320 frommovement along with the ball mount 340 in the axial direction 350. (Dueto the spherical outer surface 344 of the ball mount 340, suchengagement effectively prevents further movement of the race 320 toenable disassembly of the ball mount 340 from the end fitting connectorassembly 300. Given the symmetrical design of the end fitting and thespherical surface of the ball mount 340, axial movement of the ballmount 340 in the opposite direction (not shown) would produce a similareffect.

Still other variations are possible. For example and referring to FIGS.16(a)-16(e), there is depicted an end fitting connector assembly 500made in accordance with yet another exemplary embodiment. As in thepreceding designs, the end fitting connector assembly 500 includes anend fitting 510 having a distal end 511, a proximal end 513 and an endfitting axis 515 passing through the first and second ends 511, 513. Athrough opening 514 provided between the first and second ends 511, 513of the end fitting 510 extends in a direction that is transverse to theend fitting axis 515 and is defined by a peripheral wall 518. Theproximal end 513 of the end fitting 510 includes an engagement portion527 that is configured to secure a rod end (not shown).

The end fitting connector assembly 500 according to this embodimentfurther includes a elastically deformable race 530 that is mounted orinstalled into the through opening 514 in which an exterior or outersurface of the race 530 engages the peripheral wall 518 and an interioror inner surface of the race 530 is configured and sized to engage theouter spherical surface 542 of a ball mount 540. As in the precedingembodiment, each of the interior and exterior surfaces of the flexiblydeformable race 530 are substantially spherical or at least angled.

According to this embodiment, the exterior surface of the race 530 andthe peripheral wall 518 of the end fitting 510 include aligned grooves517, 534, respectively in which the grooves 534 of the end fitting 510include angled or tapered wall surfaces, shown only in FIG. 16(b), whichupon attachment to the ball mount 540 combine to create a camming actionthat prevents or substantially restricts disassembly when the ball mount540 is moved axially. An opening 578 is provided in the exterior surfaceof the end fitting 510 that extends through the end fitting 510 to theperipheral wall 518 and to the spacing between the grooves 517, 534.According to this specific embodiment, the opening 578 is sized toaccommodate a release tool, such as an axial section of wire 570 orother suitably configured member that can be introduced through theopening 578 provided in the exterior surface of the end fitting 510 anddirectly into the spacing defined between the aligned grooves 517, 534.The presence of the axial section of wire 570 creates an obstructionthat prevents the camming action between the surfaces of the elasticallydeformable race 530 and the end fitting 510 and more easily permitsdisassembly of the ball mount 540 from the end fitting connectorassembly 500. Another embodiment of an end fitting connector assembly600 is depicted in FIGS. 17(a) and 17(b). As in the preceding, theconnector assembly 600 similarly includes an end fitting 610, such as aclevis or similar component, having a distal end 611, a proximal end 613having an engagement portion 627, and a through opening 614 that extendsin a direction that is transverse to an end fitting axis extendingthrough the distal and proximal ends 611, 613. An elastically deformablerace 630 is a ring-like member including an outer surface 634 thatengages a peripheral wall 618 of the through opening 614 and an innersurface 638 that is configured and sized to engage the outer sphericalsurface 674 of a ball mount 670 in a snap fitting arrangement. Similarto the embodiment previously described with regard to FIGS. 2-5, forexample, each of the inner and outer surfaces 638, 634 of the race 630are defined by a spherical configuration wherein the outer surface 634of the race 630 includes an annular circumferential ridge 639 which isconfigured to engage a continuous groove 650 that is defined in theperipheral wall 618 when the ball mount 670 is snap fitted to theassembly 600. The foregoing feature insures that when assembled, theelastically deformable race 630 is disposed in a predetermined position.

According to this embodiment, a pair of openings 640 are provided in theexterior surface of the end fitting 610 that extend into the assembly600 and between the elastically deformable race 630 and the peripheralwall 618 of the end fitting 610 at spaced portions thereof. The openings640 are spaced axially from one another on opposing sides of the groove650 and annular ridge 639 that secures the race 630 to the end fitting610. In terms of operation, axial sections of locking wire(s) 660 areprovided and inserted into each of the openings 640, the locking wires660, FIG. 17(b), being disposed between the race 630 and the end fitting610 to prevent engagement between the ball mount 670 and the race 630when the ball mount 670 is pulled from either axial direction via thethrough opening 614 and permitting disassembly of the ball mount 670from the end fitting 610 portion of the assembly 600.

Yet another variation of an end fitting connector assembly 700 isdepicted in FIGS. 18(a)-18(d). According to this specific embodiment andsimilar to prior versions, the end fitting connector assembly 700includes an end fitting 710 that is defined by a transverse throughopening 714 formed in a distal end having a peripheral wall 718 that issized and configured to accommodate an elastically deformable race 730.The elastically deformable race 730 is defined by a ring-like memberhaving an outer surface 734 and an inner surface 738 in which the outersurface 734 further includes a circumferential raised ridge 740 at aboutthe center thereof configured for engaging a groove 750 formed in theperipheral wall 718 of the end fitting 710. The latter groove 750,according to this embodiment, is further defined with tapered walls ateach end of the groove 750 which create a resistance force against therace 730 and more specifically the circumferential raised ridge 740following assembly. In this embodiment, each of the circumferentialraised ridge 740 of the race 730 and the groove 750 of the end fitting710 further include an additional annular groove or notch 744, 748,respectively, each of the grooves 744, 748 being aligned with oneanother upon assembly.

In this embodiment, a wire clip 780 defined by a ring-like configurationis initially provided within the annular groove 748 defined in theperipheral wall 718 of the end fitting 710. The wire clip 780 extendsalong substantially the entire circumference of the groove 748 and hasrespective ends 784 that extend to a projecting portion of the endfitting 710 and more specifically a through opening 788 of the endfitting 710 that extends transversely to the axis of the through opening714. When assembled, a ball mount 770 includes an outer sphericalsurface 774 that is engaged by the inner surface 738 of the race 730 ina snap-fitting engagement.

In terms of operation and referring to FIGS. 18(a) and 18(b), the wireclip 780 is initially radially biased such that the wire clip 780 isentirely positioned within the defined groove 748 of the end fitting710, as shown most clearly shown in FIG. 18(b). In this position, theinner surface 738 of the elastically deformable race 730 is engaged withthe outer surface 774 of the spherical ball mount 770 and thecircumferential raised ridge 740 of the race 730 is engaged within thegroove 750 of the peripheral wall 718 of the end fitting 710. In thisposition, the race 730 is constrained into engagement with the endfitting 710 and the ball mount 770 in a manner that prevents disassemblywithout concerted effort or as in this embodiment, a tool.

More specifically, the outer circumferential ridge 740 of the race 730is retained within the groove 750 defined by the end fitting 710 and theangled end walls of the groove 750 prevent the race 730 from movement inthe direction along the axis 778 of the through opening 714 andcorrespondingly prevent movement of the ball mount 770 against theconstrained race 730.

When a tool (not shown) is placed into the opening 788 and intoengagement with one of the extending ends 784 of the wire clip 780, asshown in FIGS. 18(c) and 18(d) in the direction 794, a peripheralportion of the wire clip 780 is at least partially released from thegroove 748 of the end fitting 710 and becomes at least partiallydisposed within the aligned groove 744 of the race 730. This latterposition creates locking engagement between the race 730 and the endfitting 710, preventing relative movement. As a result, the outerspherical surface 774 of the ball mount 770 can easily move against theinner surface 738 of the race 730. As a result, the ball mount 770 canbe easily disassembled. According to one version and with the endfitting connector assembly 700 supported against a fixed surface (notshown), the entering tool upon engaging the extending end of the wireclip 780 can be rotated in the direction 794 that facilitates thisdisassembly in either direction 797, 799 of the through opening 714.

Yet another alternate embodiment of an end fitting connector assembly800 is depicted in FIGS. 19 (a) and 19 (b). This assembly 800, like thepreceding, includes an end fitting 810 defined by a distal end and aproximal end, the distal end being further defined by a transversethrough opening 814 having a peripheral wall 818. An elasticallydeformable race 830 is further provided having an outer surface 834 andan inner surface 838 in which the inner surface 838 is defined by aspherical or substantially spherical configuration that is configuredfor engaging the outer spherical surface 874 of a ball mount 870. Acircumferential raised ridge 840 formed on the outer surface 834 of therace 830 is compressively engaged with the peripheral wall 818 of theend fitting 810 upon assembly, the latter wall 818 including a profilehaving a plurality of stepped surfaces 845, 847 spaced from a groove ornotch 850 disposed at about the center of the axial span of theperipheral wall 818.

According to this specific embodiment, the circumferential ridge 840 ofthe race 830 is further defined by a notch or groove 842 at about thecenter of the ridge 840, each of the grooves 842, 850 beingsubstantially the same width dimension. The first pair of steppedsurfaces 845 of the peripheral wall 818 of the through opening 814define a first recessed portion 888 that is sized to accommodate theraised circumferential ridge 840 and permit limited movement of the race830 in either axial direction 890. The second set of stepped surfaces847 according to this embodiment extend radially inward and define anadditional recessed portion 889.

A wire clip 880 is initially disposed within the end fitting 810 andmore specifically within the groove 850 of the end fitting 810, the wireclip 880 having a diameter that enables same to be fully and solelyretained within the groove 850 initially. As shown in FIG. 19(a), theelastically deformable race 830 in the initial assembled condition cantranslate slightly along in either axial direction relative to thethrough opening 814 of the connector assembly 800 within the recessedportion 888, but is prevented or at least constrained from furthermovement based on this geometry. Based upon this constraint, onlylimited movement is permitted between the ball mount 870 and the race830 and disassembly is made difficult without the application of agreater amount of force than required for purposes of assembly.

When the wire clip 880 is acted upon, for example in the mannerpreviously illustrated according to FIGS. 18(c) and 18(d) using a tool(not shown), and as shown in FIG. 19(b) at least a peripheral portion ofthe wire clip 880 is caused to move radially inward, away from theconfines of the groove 850 of the peripheral wall 818 of the end fitting810 and at least partially into the groove 842 formed on thecircumferential raised ridge 840 of the race 830. In this latterposition, the race 830 becomes effectively locked meaning that the race830 is prevented from any movement independent of the end fitting 810 inthe direction 890. Therefore, the ball mount 870 is not constrained bythe race 830 and can be easily disassembled in either direction 890.

Minimally, each of the elastically deformable races described in theprior embodiments can be formed from a plastic material in whichfabrication by molding can facilitate manufacture, including the salientfeatures such as the inner and outer surfaces as well as thecircumferential outer edge and the grooves. According to anotherexemplary embodiment and referring to FIGS. 20(a)-20(c), another endfitting connector assembly 900 can be provided that includes an endfitting 910 defined by a transverse through opening 914 and a peripheralwall 918 and an elastically deformable race 930. According to thisspecific embodiment, the race 930 is defined by a ring-like section madefrom a metal, such as bronze or steel, having a through opening that isaligned with the through opening 914 of the end fitting 910, whenassembled. The peripheral wall 918 of the end fitting 910 includes anannular groove 950 disposed at about the center of the axial dimensionof the through opening 914. The groove 950 according to this specificembodiment is defined by a substantially concave configuration.

The race 930 is defined by a thin ring-like structure including an outersurface 934 and an inner surface 938, as well as opposing first andsecond ends 943, 945. Each of the first and second ends 943, 945,including the outer and inner surfaces 934, 938, are mirror images ofone another and are commonly defined by a plurality of spacedcastellations 935 equally spaced and arranged circumferentially. Eachcastellation 935 according to this embodiment is a cantilevered springhaving an outer end 939 that is reflexed radially inward relative to aninner end 941. Each of the inner ends 941 of the castellations 935 oneach side 943, 945 of the race 930 terminate commonly to a centerconcave portion 954 extending radially outward and initially retainedwithin the groove 950, when assembled, as shown in FIG. 20(a).

In operation and referring to FIG. 20(a), the race 930 is shown asassembled and in which the radially protruding center portion 954 of therace 930 is engaged with the groove 950 formed in the peripheral wall918 of the transverse through opening 914 of the end fitting 910 in thedirection 990. It should be noted that assembly can proceed from eitheraxial end of the herein described assembly 900. As the ball mount 970 isengaged at one of the ends 943 of the assembled race 930, the outerspherical surface 974 of the ball mount 970 directly engages the outerends 939 of the spring-like castellations 935 causing the outer ends 939on that side 943 of the race 930 to deflect radially outward toward theperipheral wall 918. As the ball mount 970 is further advanced in theaxial direction 990, the spherical contour of the outer surface 974causes the outer ends 939 of the castellations 935 to additionallydeflect elastically and further causing the race 930 to pivot about theconcave projecting portion 954 within the groove 950. This pivotingaction enables the ball mount 970 to be fully assembled into theposition shown in FIG. 20(b). In this position, the race 930 isprevented from axial movement by the peripheral wall 918 of the endfitting 910 and more specifically the engagement of the protrudingportion 954 of the race 930 within the groove 950 of the peripheral wall918 of the through opening 914 and the spherical outer wall 974 of theball mount 970. Due to the tapered geometry of the castellations 935 andthe biasing forces provided, disassembly is thereby prevented withoutuse of a tool or at least from occurring easily using a greater appliedforce than that applied during assembly.

It will be readily apparent that other modifications and variations canbe contemplated to be adequately covered by the inventive concepts thatare described herein, including the following claims.
